![]() ![]() Learn more about Light and its properties Wavelength of 400-700 nm means a frequency range of around 430-750 Terahertz (THz).Visible light has wavelengths that range from 400-700 nm (nanometers) or 4.00 x 10 -7 m to 7.00 x 10 -7 m, between the infrared waves that have longer wavelengths and the UV rays that have shorter wavelengths.Photons are the smallest quantity of energy that can be transported.Electromagnetic spectrum radiation is defined as a stream of photons – particles that have no mass travelling with wavelike properties at the speed of light. ![]() Visible light is not very different from other parts of the electromagnetic spectrum except that it can be detected by the naked human eye.Units and Measurements Detailed Video Explanation Electromagnetic radiations are the fluctuations of magnetic and electric fields that transport energy from one location to the other.It plays a fundamental role in the natural world and is used in a wide range of applications, from lighting and communications to medicine and materials science.In addition to being visible, light can also be detected by other norms, such as through the use of cameras, telescopes, and other scientific instruments.Light is able to travel through a vacuum. ![]()
